Equivalent & Substitute Parts for 1M110Z Zener Diode

Part Overview

The 1M110Z is an active-status zener diode manufactured by Taiwan Semiconductor Corporation, rated for 110 V nominal zener voltage with 1 W maximum power dissipation in a DO-204AL (DO-41) through-hole axial package. This component is designed for voltage regulation and protection applications requiring precise 110 V reference voltage maintenance. Substitute parts are identified to provide equivalent functional performance with alternative electrical characteristics or packaging configurations while maintaining core application compatibility.

Substitute Part Grouping Explanation

Substitute parts for the 1M110Z zener diode are qualified based on the following critical parameters:

Matching Criteria:

Zener voltage (nominal): 110 V
Voltage tolerance: ±5%
Package type: DO-204AL (DO-41) through-hole axial
Operating temperature range: -55°C to 150°C
RoHS3 compliance status
Mounting configuration: Through hole

Substitution Logic: The identified substitute parts (Z4KE110A-E3/54 and Z4KE110A-E3/73) maintain identical zener voltage specification and tolerance, identical package configuration, and identical operating temperature range. These substitutes are qualified for direct replacement in applications where the 1M110Z is specified. The substitute parts feature enhanced power dissipation capability (1.5 W versus 1 W) and improved impedance characteristics, providing superior performance margins in voltage regulation circuits.

Engineering Selection Recommendations

The 1M110Z and its identified substitutes (Z4KE110A-E3/54 and Z4KE110A-E3/73) are all active-status components with ROHS3 compliance certification, confirming current manufacturing availability and regulatory alignment. All three parts maintain identical zener voltage specification (110 V ±5%), operating temperature range (-55°C to 150°C), and DO-204AL package configuration, establishing direct functional compatibility for through-hole circuit board applications.

The substitute parts from Vishay General Semiconductor provide enhanced electrical performance through increased power dissipation rating (1.5 W versus 1 W) and reduced reverse leakage current (500 nA versus 5 µA), delivering improved stability in voltage regulation circuits. These performance enhancements do not compromise compatibility with existing circuit designs specified for the 1M110Z.

Packaging format differences exist between the main part (Tape & Reel) and substitutes (Cut Tape), reflecting different supply chain configurations rather than functional differences. Component selection should be based on procurement requirements and circuit application demands.

Frequently Asked Questions (FAQ)

Q: Can Z4KE110A-E3/54 and Z4KE110A-E3/73 be used as direct replacements for 1M110Z in existing designs?

A: Yes. Both substitute parts maintain identical zener voltage (110 V ±5%), operating temperature range (-55°C to 150°C), and DO-204AL package configuration. Direct pin-for-pin and functional substitution is supported for through-hole circuit board applications.

Q: What are the differences between the two Vishay substitute parts?

A: Z4KE110A-E3/54 and Z4KE110A-E3/73 are electrically identical. Both feature 110 V zener voltage, 1.5 W power rating, and DO-204AL packaging. The part number suffix indicates different packaging tape specifications or supply chain designations from Vishay General Semiconductor.

Q: How do the electrical characteristics of the substitutes compare to the 1M110Z?

A: The substitute parts provide enhanced performance: power dissipation increases from 1 W to 1.5 W, and reverse leakage current decreases from 5 µA to 500 nA. These improvements provide superior voltage regulation stability and reduced standby current consumption without affecting core zener voltage specification.

Q: Are there packaging considerations when substituting these parts?

A: The 1M110Z is supplied in Tape & Reel format, while Z4KE110A-E3/54 and Z4KE110A-E3/73 are supplied in Cut Tape format. Both formats are compatible with standard through-hole assembly processes. Procurement and inventory management procedures may require adjustment based on packaging format preference.

Q: Do all three parts meet the same regulatory compliance standards?

A: Yes. The 1M110Z, Z4KE110A-E3/54, and Z4KE110A-E3/73 are all ROHS3 compliant and REACH unaffected, confirming equivalent regulatory status for applications requiring environmental compliance certification.

Q: What is the impedance difference between the main part and substitutes?

A: The 1M110Z has a maximum impedance of 450 Ohms, while the substitute parts specify 600 Ohms maximum impedance. This difference reflects manufacturing tolerance variations between manufacturers and does not affect functional compatibility in standard voltage regulation applications.
